SHADE-HOLDER.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed June 13, 1910. Serial No. 566,669.

To all whom it may concern:

Be it known that I, I/VALTER H. PERKINS, a citizen of the United States,residing at Cheshire, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement inShade-Holders; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, iii- Figure l a view in front elevation of my improvedshade-holder, showing it as ap plied to a lamp-socket. Fig. 2 a detachedview in side elevation of the socket. Fig. 3 a detached view in sideelevation of the clamping-ring. Fig. 4 a detached plan view of theshade-holder proper. Fig. 5 a broken view in vertical section on anenlarged scale, showing the clamping-ring in its operative position.

My invention relates to an improvement in shade-holders for incandescentlamps, the object being to provide at a low cost for manufacture, asimple, convenient and effective shade-holder for the purpose described.

With these ends in view my invention consists in a shade-holder havingcertain details of construction as will be hereinafter described andpointed out in the claim.

In carrying out my invention as herein shown, I construct theshade-holder with an upwardly extending socket-receiving collarconsisting of three corresponding segmental collar-sections 2respectively formed upon the inner edges of yoke-like horizontal arms 3terminating at their outer ends in a depending flange or skirt 4: intowhich the upper edge of the shade is inserted for retention in place byscrews 5 mounted in perforated lugs 6 depending from its lower. edge inthe usual manner. The said arms 3, and hence the collar-sections 2, areseparated from each other by vertical slots 7 leading at their outerends into relatively large horizontal clearance slots 8 located in thehorizontal plane and giving flexibility to the arms 3. The saidcollar-sections 2 are formed with an outwardly projecting knurl 9 forthe reception of a circumferential head 10 at the lower end of thelamp-socket 11. p The said bead 10 of the socket 11 is crowded downwardinto the knurled portions 9 of the collar-sections 2 which are by itsprung outward until it enters them after which they spring back andover it and clasp it as shown in Fig. 5. The bead 10 is then firmlylocked in place by the sleeving of a clamping-ring over the upper endsof the collar-sections 2 as plainly shown in Figs. 1 and 5, it beingthen retained in place by the flaring upper edges of thecollar-sections. The said clamping ring is made in one piece andcomprises an inwardly extending circumferential bead 12, aretaining-edge or flange 14 extending upward and inward from the upperedge of the said head for co-acting with the upper ends of the collarsections, and with a downwardly and outwardly extending operating flange15 by means of which the ring is engaged by the fingers, or an implementsuch as a knife or screw-driver, for lifting it or prying it over theupper ends of the yielding collar-section 2 so as to permit the bead 10to be drawn out of the knurl 9 of the collar-sections.

I am aware that it is not broadly new to apply a knurled clamping-ringto yielding fingers forming a part of a shade-receiving ring and adaptedto receive between them a bead formed at the lower end of a lampsocket.I do not therefore claim such a con struction broadly, but only myparticular construction.

I claim In a shade-holder for incandescent lamps, the combination with ashade-receiving ring provided with a socket-receiving collar divided byvertical slots into yielding collarsections collectively having anoutwardly projecting knurl for receiving a bead upon the lower end of alamp socket; of a clamping-ring adapted to be sprung over the upper endsof the said collar-sections, and having an inwardly projecting bead, anupwardly extending and inwardly turned retaining-flange located abovethe same, and an outwardly turned lifting-off flange extending below thesame.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.

WALTER H. PERKINS.
